WIRE-FENCE MACHINE.

Specification of Letters Patent'.

Patented March-26, *1907.

To a/ZZ whom it may concern:

Be it known that I, 'AXEL F. BAGKLIN, of Worcester, Worcester county, Massachusetts, have invented a new and useful Improvement in Wire-Fence Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying draW- ings, forming part of this specification, in whichi l Figure 1 is a horizontal section of one form of fence-machine to which my invention is applicable: Fig. 2 is a vertical section on' the' line II II of Fig. l. Fig. 3 is a detail view of the pawl-and-ratchet mechanism forFactuati ..4 is a similar view taken from the opposite? side. Fig. 5 is a plan view of the same. Fig. 6 is a vi'ew of a modified form of false ratchet. Fig 7 is a sectional elevation of the take-up device or vibrator. Fig. 8 is a section on the line VIII VIII of Fig. 7, and Fig. 9 is a side elevation of the upper portion ofthe machine with `the take-up rollremoved.

My invention has'relation to thatclass of Wire-fence`machines in'which a series of longitudinal or strand wires are' fed longitudinally through themachine and a series of transverse or stay wires are fed thereto at intervals and are secured to the strand-wires by the action of twisting or looping devices.

'An object of the invention is to provide means whereby the spacing of the stay-wires may be varied as desired, the change from me spacing to another being capable of being quickly and readily made. v I My invention consists, broadly, in the provision of means for preventing the operation of the stay-wire-feeding devices except at proper intervals, the other Yparts of themachine being arranged `to perform continuously'th'eir proper cycles of operation. By thus preventing the operation of the stay- Wire-feeding devices except Vat the predetermined intervals the distance to which the longitudinal strand-wires are advanced between the times of feeding the stay-wires` may be varied as desired.

Referring iirst to Fig. 1, the longitudinal or strand wires are fed into the machine through the guides 2 and 3 to the point'll, where they receive the sectional stay-wires, which are applied thereto by means of suitable ceiling or twisting devices, (indicated at 5.) These through the guid they are acted upon by the coilers 5.

devices may be of the character employed in the well-known Bates machine, as shown and described in patents to A. J. Bates, Nos. 577,639, dated, February 23, 1897, and 591,996, dated October 19, 1897, and need not ybe speciiically described herein, as they constitute no part of the present invention.

6 and 7 designate the usual crimping-rolls, which are continuously driven through the gearing 7L and 7b from the shaft 20, hereinafter further referred to, and 8 and 9 are two xed guide-rolls which are located between the crimping-rolls and the looping or coiling devices 5. I

l0 designates the vibrator or take-up roll, which is arranged intermittently of the fixed guide-rolls 8 and 9 and which is arranged to reciprocate toward and away from the same' and transversely of the line ofmoveinent of the fence fabric in order to form a loop or bight thereinas it comes from the coilers to provide an eXtra length of fabric stored up between the coiler's and the take-up roll 11, so that the latter may be driven continuously irrespective of the intermittent movement of the strand-wires through the coilers. This take-up device or vibrator is in general of the form and arrangement shown in the patent to Backlin and Elrlund, No. 807,652, of December 19, 1905, to which reference may be yhad for a full description, with certain slight mechanical modifications hereinafter described. f A

The sectional stay ires are fed in the usual manner thrcu the guides 12 and the feed rollers or whe s 13 and 11i and thence 15 to the point 1l, where l The feed-rollers 13 and 14 are actuated by means of the gears 16 (shown in Fig. 2) from a vertical shaft 17, whichearriesahits upper end a bevel-pinion 18,'1neshing with a bevel gearwheel 19 on the longitudinal shaft 20. This shaft 20 has fixed thereto a ratchet-wheel 21 and'is actuated by .means of a pawl 22,p ivoted on the center 23 and moved by a pitman 24, connected to a crank-pin 25 of a crankwheel 26, mounted on a shaft 27, which is parallel with the shaft 20 and which is driven IOO from the main driving-shaft of the machine.

ratchet-wheel 21 is a, false ratchet 28, which I is to hold the paWl 22 out of engagement with A is provided with a series of teeth 28, shallowT depressions 28h, and deeper depressions 28C, the latter registering With the teeth of they ratchet 21. rlfhe'purpoee of this false ratchet the ratchet 21 except at those teeth of the latter which register with the deeper depressions 28 of the false ratchet, so` that the shaft 20, and thereby the shaft 17 and the stay-wire-feeding rollers driven thereby, will be actuated only at these times. The pawl 22 has its engaging end sufficiently broad to cover the peripherie's of the ratchet 21 and thefalse ratchet 28. 294 is a pawl which engages the false ratchet 28 for' the purpose of preventing back movement or lash thereof. The false ratchet is made in two' separable parts secured together by bolts-3l), as shown 1n Fig. 4, so that it can be 'uickly removed from the shaft 2() and anot er ratchet of a dierent pattern--such, for instance, as that shown in Fig. 6-be substituted therefor for the purpose of varying the intervals at which the stay-Wire-feeding devices are actuated..l 31 and 32 designate suitable gearing for operating the coilers or loopers. These gears are actuated by a shaft 32a, carrying a gear 33 driven by a bevelfear 34 on a shaft 35, which is parallel Wit the shaft 20. The shaft 35 is actuated by va paWl-and-ratchet movement 36. (Shown in dotted lines .in Fig. 2.) n The vibrator or take-u roll 10 is journaled at its ends in heads 38, W ich are arranged to slide on the guides 39, as shown in Fig. 7. Each of these heads is provided With an arm 40, which carries a roller 41, which engages a cam-groove 42 ef a cam 43, secured to the actuating-shaft 44. This shaft carries tivo of the cams 43, and the cam-grooves 42 of such character that as the shaft 44 is rotated the heads-38 will be reciprocated on the guides 39 toward and. away from the guide-rolls 8 and 9,. thereby carrying the fabric back between said rolls in the manner shown b-y the dotted lines of Fig. 1 to form a bight or loop therein. As above stated, this arrangement is substantially that of the Patent No. 807,652, cams being substituted for cranks in the actuating-shaft.

As will bereadily understood., the take-up roll 1 1 is driven continuously, as by a belt 45, passing from a band-Wheel 46011 the shaft of the drum 7 around a pulley 47 on the shaft of. the take-up roll,` the vibrator' acting to provide the necessary slack in the fabric to enable the take-up device to continue to operateMWhile the coilers are acting to secure the stay-Wires. The action of these coilers is in all respects the same as in prior machines, and, in fact, all the parts of the machine operate in their usual and regular cycles, the 0peration of the stay-Wirefeeding devices being varied, as above described, to vary the 65 spacing of the stay-Wires.

' Wire-feeding devices, and coiling mechanism,

lt will be readily understood thattheinterruption in the operation of the sta4 -Wirefeeding devices may be accomplished in various Ways, as by providing means whereby the two series of feed rollers or Wheels 13 and 14 may be separated at intervals. to prevent their feeding action upon the stay-Wires, also that various arrangements of gearingmay be provided to secure this intermittent action of the sta'y-Wire-feeding devices. 7 o

lVhile l have shown my invention as applied to a machine of the Well-known Bates type, as shown in .the patents above mentioned, it Will be apparent that it may be applied to any field-fence machine, Whether or not the crimping and take-u drums have a constant or intermittent motion and Whether or not a vibrator is employed.

W hat l claim is-- 1. In a Wire-fabric machine, continuouslyoperating strand-wire-feeding mechanism, and intermittently-operating stay-Wire-feeding mechanism having means wherebyl its pe'- riods of operation may be' varied Without :l fec'ti'ng the operation of the strand-Wire feed; substantially as described.

In a Wire-fabric machine7 the combination with continuously-operating stran i Wire-take-up mechanism, of a series of stay- Wire-feeding Wheels or rollers, and gearing for actuating the same intermittently, said gearing havin a removable controlling member by changing which the intervals of operation of the gearing and the consequent spacing of the stay-wires may be varied gsubstantially as described.

In testimony whereof I have hereunto set my hand.
